Ken (the other designer of Hexels doing all of the code) added a feature to Hexels that I’ve begged for for weeks! In isometric cube mode, the hexels become cubes and you can use 3 colored light sources to tint the cube’s sides. You can either make the light sources occupy a point in space (local) or they can be directional lights (global). The pink/lavender/light-blue boxes in the above drawing are actually white boxes with directional lights of those colors.
It is done in a Q*bert fashion because the boxes still occupy the original positions of the hexels. This will be an on-going theme for the other features in Hexels that I’ll talk more about later.
